Description

Motor vehicle wind-assisted braking device

The utility model relates to a safety device for a motor vehicle, in particular to a wind-assisted braking device for a motor vehicle. Second, the background technology

Motor vehicles bring great convenience to people's travel, but their safety has always been a technical problem that plagues people. Nearly one million people die every year in the world and are injured in car accidents. The long braking distance of motor vehicles is a major problem. In the development of the world's automobiles, the power of speed is no longer a problem. Both volumetric power and weight-to-weight power have reached a very high level. The development of relevant road technology and the background facilities have provided a good premise for the development of the car speed. Only the braking technology of the car restricts the speed of the car.

At present, the publicly used brake technology includes the ABS anti-lock brake system. The EBD uses the brake pad as the stator part and the brake disk as the rotor part. When braking, the friction plate is pressed by the hydraulic system to cause a frictional relationship between the rotor and the stator to achieve the purpose of braking. The technical core of the ABS system is to control the rotor part in an optimal state by means of electronic technology so that the motor vehicle does not pull the tire with the ground. Once the tire is pulled, it means that the pressure on the friction piece belonging to the stator part is too large, and the rotor and the stator form a locked state, so that the braking effect is drastically reduced, so that the braking distance is increased, so the ABS anti-lock system The dynamic system is still in the range of fine-tuning effects.

The ABS anti-lock brake system can only use the rated body weight through electronic technology, so that it does not occur when braking, reaching the maximum physical limit of the body weight. The disadvantage is that the braking distance is longer. For example, the Mercedes-Benz S350L car has a braking distance of 46.6 meters at 100 km/h ("Car Magazine" 2003's March issue 61 pages). The reason why the braking distance is too long is that the weight of the car body is rated. Even if the permanent rear weight is increased, the fuel consumption will increase greatly, the power consumption burden will be too heavy, and the weight increase will also increase the forward inertia. Force, do not succumb to positive braking measures.

Since the friction of the brake system is determined by the weight of the vehicle body, the frictional pressure of the tire on the road surface is a prerequisite, and the friction pressure between the brake pad and the disk is set according to the friction pressure of the tire on the road surface.

The Porsche's car tail technology from Germany is permanently exposed to the upper rear of the rear trunk.

The working principle of the wind-assisted braking device for a motor vehicle of the present invention is as follows: As shown in FIG. 13, the main windward surface 1 receives the air flow 13 from the roof direction at an angle of working state, with a certain angle The front windshield 15 squeezes the air in this space at a speed of more than 100 kilometers per hour. The pressurized air moves rearward and upward along the front windshield 15 and the pressure is relieved when the rear end contacts the pressurized air. The vacuum direction of the rear space meets the higher density of the squeezed air, forming a certain angle of air flow 13 flowing backwards and backwards of the tail, the angle formed by the direction of the air around the flow 13 and the tail The inner layers are approximately parallel. The inner angle of the rear end is approximately 45 degrees from the horizontal direction of the road. The inner angle surface of the rear end is approximately 90 degrees from the main windward surface 1 that is suddenly opened to the working angle state. More than 100 kilometers per hour, air flow 13 High-pressure high-density air formed from the roof, the left and right sides of the car, and the three directions. After the air around the air 13 hits the main windward plate 1, it will disperse along the main windward surface 1 in the up, down, left and right direction, and continue to the main windward surface 1 after the brake is completed or halfway. The air flow 3 acts on the main windward surface 1 to generate a force to the rear and the rear of the vehicle. According to the mechanics principle, the force can decompose two components, one is the backward horizontal component, and the horizontal component is Direct deceleration can greatly reduce the braking distance of the motor vehicle and improve the safety performance of the motor vehicle. The other is the downward vertical component force. The vertical component force can increase the pressure on the road surface of the rear wheel of the car to improve the pressure. Friction with the road surface, through the brake system to achieve the purpose of deceleration. At a speed of 100 km/h, the main windshield per square meter can generate about 100 kg of vertical pressure on the road surface. In the state of 200 km / h, the pressure on the road will increase several times. The caliper and friction disc force for braking systems such as the ABS system can be increased accordingly, providing a prerequisite for improved braking efficiency. When the speed is between 100 km/h and 60 km/h, the braking efficiency is the initial stage, and the braking distance is shortened by about 35 %. In the 200' km/h state, the braking distance can be shortened by 35 %.
